I get this issue when i run my xcode Project. i will start the project and the simulator will load but as soon as it loads up the app i am making it crashes.
This is the error code :Thread 1: Exception: "unable to dequeue a cell with identifier ChecklistItem - must register a nib or a class for the identifier or connect a prototype cell in a storyboard"
and says this in the terminal:

Answer 1

Based on the error, you did not register the cell when setting up the tableview.
Check the documentation:
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "DefaultCell")
Or
tableView.register(UINib(nibName: "yourNib", bundle: nil), forCellReuseIdentifier: "CellFromNib")
Just fill in the proper values for cell, nibName, identifier, etc... Depending on which method you're using
And here is a link to a guide if you need a bit more info: link
